SHARON HOSPITAL, SHARON, CONN.
All layers of new polyisocyanurate insulation were installed using Garland’s Insul-Lock HR high-rise insulation adhesive. The new insulation system met all international building codes for R-value and proper drainage. Oversized 20-foot tapered sumps were built around the hospital’s internal drains to provide additional drainage.
Garland’s StressBase 120 SBS modified base sheet was installed over the recovery board using Green-Lock cold-applied, zero-VOC membrane adhesive. The top ply of the system is Garland’s Millennium FR Mineral fire-resistant, SBS, coal-tar modified membrane.
The leaking 5,500-square-foot roof was 30 years old—almost as old as the hospital itself. It was built as an inverted roof membrane assembly, which is essentially an “upside-down” design with the insulation on top of the roof plies. Over time, the roof began deteriorating, causing severe leaking at the base of walls and penetrations.
There were several factors to consider while developing a new solution, including the low through-wall counterflashings, high wind-uplift and the fact that the roof is directly above the hospital entrance.
“The duration of the project needed to be at a minimum since the set up and staging area was directly in front of the main hospital entrance where patients are picked up and dropped off. It was also critical to make sure there were absolutely no unpleasant odors,” says Steve Botelho, The Garland Co. Inc.’s local rep.
Botelho coordinated removal of the original roof and construction of the new roof with Quality Improvements to ensure it was completed within the scheduled two-week timeframe.
Brian Croghan, Sharon Hospital’s director of facilities, notes: “Once the contractor got set up on the roof, the disruption below was virtually nonexistent, which was really nice. That coupled with the fact that there was no odor helped make the entire project a very positive experience.”
